Lead member

A lead member comprising:

• a lead conductor having a first main surface and a second main surface that is an opposite side of the first main surface;
• and
• a resin portion including polypropylene, while exposing both end portions of the lead conductor in a first direction, covering the first main surface, the second main surface, and both side surfaces between the both end portions of the lead conductor,
• wherein the lead conductor includes
• a metal substrate made of aluminum or an aluminum alloy, and
• a colored layer including a black anodic oxide coating formed on a surface of the metal substrate,
• wherein in an entire wavelength band of 220 nm or more and 850 nm or less, when a total reflectance of barium sulfate is defined as 1.0, a regular reflectance of the black anodic oxide coating is 0.2 or less, and
• wherein the colored layer is provided on an entirety of the first main surface and the second main surface.

• wherein the lead member includes
• a metal substrate made of nickel-plated aluminum, a nickel-plated aluminum alloy, nickel-plated copper, or a nickel-plated copper alloy, and
• a colored layer including a black nickel-plating layer formed on a surface of the metal substrate and having an arithmetic mean peak curvature Spc of 5000 mm−1 or more that is measured in accordance with ISO 25178,
• wherein in an entire wavelength band of 220 nm or more and 850 nm or less, when a total reflectance of barium sulfate is defined as 1.0, a regular reflectance of the black nickel-plating layer is 0.2 or less and
• wherein the colored layer is provided on an entirety of the first main surface and the second main surface.
